Have a user that has an excel file emailed to them from another user. They open the file and add some formulas to it and save it to a folder and then email it back to the other user. That user (the one that emailed it in the first place) edits some of the formulas and creates new ones and types some info in the file and when they email it back to the user that created the formulas, the formulas are not there. I know it sounds weird but that is what THEY say is happeing. I have not witnessed this with my own eyes. Any ideas?
